Okay, I tried several times for the second cross tab query to work, yet it splashes the same error. I have the form open for its reference. I have both the queries open, and the first one filters the results when the center code is selected from the form, but the second one. i.e. the crosstab gives the same error I showed above. I can't resolve this and do not know what direction to take now.
